The $\varphi (2170)$ production in the process $\gamma p\to \eta \varphi p$

Abstract

We have studied the $\gamma p\to \eta \varphi p$ reaction within the effective Lagrangian approach, and our results show that there may be a peak, at least a bump structure around 2180 MeV associated to the resonance $\varphi (2170)$ in the $\eta \varphi$ mass distribution. We suggest to search for the resonance $\varphi (2170)$ in this reaction, which would be helpful to shed light on its nature.
